ATLANTA (AP) -- Scooter Gennett hit a grand slam and the Cincinnati Reds beat struggling Julio Teheran and the Atlanta Braves 11-8 on Saturday night.
Teheran, expected to be the Braves' ace for a fifth straight year, set an Atlanta record by losing his ninth straight home decision. He dropped to 1-9 with a 6.98 ERA in 13 starts at SunTrust Park.
Gennett's 21st homer, his third grand slam this season and fourth of career, made it 11-4 in the ninth. The Braves scored four runs in the bottom half, but Michael Lorenzen, the second Cincinnati pitcher of the inning, earned his second save after Blake Wood failed to retire a batter and allowed the four runs.
Robert Stephenson (1-4) gave up three hits, three walks and two runs - one earned - in five innings. He struck out five, but had some struggles, dropping a ball at first base, hitting a batter and throwing a bunt attempt into the Atlanta dugout.
Cincinnati took a 4-1 lead in the fourth on singles by Eugenio Suarez and Scott Schebler. Braves center fielder Ender Inciarte overran Suarez's hit and the ball got past him for a two-base error that scored another run.
Schebler went 3 for 4. Billy Hamilton and Joey Votto each added an RBI.
Teheran (7-11) allowed eight hits, three walks and five runs - four earned. He struck out seven and has dropped five straight decisions overall.
The Braves scored on Brandon Phillips' 11th homer, Inciarte's sacrifice fly, Kurt Suzuki's 13th homer and Matt Adams' three-run, pinch-hit homer in the ninth.
Teheran topped the Atlanta mark held by Craig McMurtry in 1984 and tied by Shelby Miller in 2015. The Braves dropped to 9-22 since reaching .500 on July 16.

TRAINER'S ROOM
Reds: SS Zack Cozart is limping considerably after getting hit in the leg with a pitch Friday and leaving the game early.

Cozart has been on the DL twice this year with strained right quad.
Braves: Kemp was reinstated from the disabled list and went 1 for 5. ... LHP Luke Jackson was placed on the 10-day disabled list with a right shoulder strain. RHP Matt Wisler was called up to take his spot.
UP NEXT

Braves: LHP Sean Newcomb (1-7, 4.45 ERA) will make his 13th career start and face Cincinnati for the first time. Since starting his career 1-2 with a 1.48 ERA in four starts, Newcomb has given up 28 earned runs and 29 walks in his last 40 1/3 innings.
